 ## Introduction
 
 The Back Pressure (BP) Gererator is a SystemVerilog UVM module which can generate back-pressure.
-It is important to note that virtual sequencer / sequences are not provided with the bp_gen package. It is up to the user to implement his/her own virtual sequencer / sequences to be able to chose between one of the four sequences provided (see sequence's part hereafter)
+The bp_gen package provides a virtual sequencer that user can use to be able to choses between one of the four sequences provided (see sequence's part hereafter).
 
 ## Configuration
 
-Users can either use one the existing sequences (see in the next part below) or create their own sequence to configure the BP type() (OFF or ON, the duration cycle and the percentage (or frequency rate))

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,

+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
